This invention relates to kitchen utensils and'more particularly tosifters for sifting flour and like materials and also for mixing withthe flour other pulverized materials such as soda, baking powder, saltVand the like in preparing the flour for special baking purposes.

An object of the invention is to produce a p sifter having a novel gripon the side forming means to support the sifter and enable it to beturned or reversed endwise.

A further object of the invention'is to provide a sifter having anendwise reversible container and a reversible sieve therein, the sievebeing provided with a sleeve which is housed within the tubular grip ofthe container and terminates in a disc by means of which the sieve maybe readily vreversed so that by reversing the position of the container,the material may be alternately sifted through the sieve in oppositedirections and fall therefrom alternately into the opposite ends of thecontainer.v

Another object of the invention is to provide novel locking meansbetween the operating disc of the reversible sieve and the tubular gripof the container, whereby the sieve may be locked stationary in eitherof the 1'e, vversed positions thereof.

Vith the above and other objects in view the invention consists incertain novel details of construction and combinations of partshereinafter fully described and claimed it being understood that variousmodifications may be resorted to within the scope of the appended claimwithout v departing from the spirit orsacrificing any of the advantagesof the invention.

In the accompanying part of this specification,

Figure 1 Vis a vertical sectional view through my improved sifter, and

Figure 2 is a cross-sectional view on the .line 2-2 of Figure 1.

k'Referring now to the y.drawing in which .like characters of referencedesignate simiv lar parts, 10 designates a container which iscylindrical in outline and is open at both ends. Covers 11 close theopposite ends o the container. A tubular grip 12 is formed drawingformmg secure the catch to the sleeve.

vintegrally with and extends laterally fromthe wall of the containerandis located substantially midway between the covers 11. The'grip formsmeans-whereby the container maybe reversed endwise so that ythe mate-yrial may be alternately sifted through thev hereinafter described sievein opposite directions. C.

' Disposed within the container is a sieve 13. The sieve is as usualformed of wirey netting V of a desired ymesh and is reinforced ,atjitsedges by a rim 111. 1

Rotatably mounted in the tubular grip 12 isa sleeve 15 preferably formedof wood or like material. The sleeve eXtendsthrough the inner yopen endof the tubular grip and projects into the container 10. Screws `16j arepassed through the rim 14 of the sieve and into the inner end of thesleeve 15 and rigy idly secure the sieveto the sleeve.` Y f The-sleeve15 terminates at fthe outer end in a'V disc 17 The disc is suficient indiam-1 eter to extend circumferentiallyy beyond the tubular grip 12 soas to be easily grasped Vby the fingers for the purpose'of rotating thev75 y sleeve and thereby reversing the sieve as will be presentlydescribed. Formed in the outer edge of the` tubular grip 12 is a pair oflongitudinal slots or .y notches 18 and 19,l these notches being -ar- 80ranged diametrically opposite each other. A radial slot or notch 20 isformed in the disc 17. A catch 21 of substantially J shape, is slidablyfitted in the notch 20 and.v is pro.- vided with al shank 22`which isreceivable in 85 a longitudinal slot 23 formed in thesleeve l 15. Y Apin 24 is passed through thel inner` end of the shank and into thesleeve to pivotallyy A Spring 2 5 is mounted in an axial recess in thesleeve 90 and bears against the' shank of the catch to yieldably holdthelatter'outwardly against the tubular grip 12. A lug 26 is formed `ontheshank of the catch and isurged by the` spring intoione ofthe notches18 or 19fat 95 each half turn` of the sleeve to 'reverse the sieve, andlocks the sieve in either of the reversed positions thereof.l

i A rotaryagitator vdeslgnated inl general bythe"numeralr 27 ismountedin thecon'- 100 tainer. The agitator comprises a plurality ofcurved arms 28 spaced about the axis of a supporting and operating shaft29. In the present embodiment four of these agitator arms are used but agreater or less num'ber may be employed. Either Wire or sheet metal maybe used in the construction. 'Ihe present embodiment employs wire. AThelongitudinal curvature of the agitator arms is such as to cause them toconform closely to the contour of the inner surface of thesleeve.

One end of the above mentioned agitator shaft 29 is j-ournaled in thewall ofthe con tainer and the opposite end is rotatably mounted inregistering openings 30 and-31 formed in the sleeve 12 and disc 17respectively. AThe outer end of the agitator shaft terminates in a crank3 2 which is equipped with a grip 33. V

Inoperation, one of the covers 11 is removedV andthe material to besifted, or sifted and `mixed, is poured into the basket-like sieve 13.The cover is now replaced and the agitator device is `rotated throughthe Inedium of the crank 32 until all of the material has been forcedthrough the sieve into the bottom of the container 10.

Thereafterthe basket-like sieve is reversed, irst-bydepressing the catch21 to withdraw the lug26V from the slot V19, as shown in Figure 2,' andthen turningythe disc 1,7 through one half revolutionuntil thelug 26 ispressed by the spring 25 intothe diametrically opposite notch 18 of thetubular grip 12. This movement of the disc 17 rotates the sleeve 15 andreverses the position of the sieve 13 so that the sieve-,is now turnedupwardly in the container.

Thereupon the entire container is endwise reversed by simply graspingtheltubular grip 1,2 in the right hand, palm upward, and

turning the wrist to turn the containerl through one half revolution.The agitator maynow again be rotated tovagain force the material throughthe sieve as above described. These operations will jbe repeated untilthe material has been suihciently s ifted or mixed.

Having thus described the invention, I claim:

A sitter comprising a container, a reversible vsieve therein, a rotarybeater therein, a tubular grip extending laterally from the containerand adapted to reverse the con- `tainer endwise, a sleeve within thegrip `lixedly secured to the sieve and adapted to reverse .the sievesaidsleeve terminating in a disk lfor rotating the sleeve, said disk havinga radial recess therein, said sleeve having a s longitudinal recesstherein communicating with the disk recess. A J-shaped catch disposed inthe recess of the disk and having an integral shank disposed in therecess of the sleeve, said shank being terminally piv- 53a otedtosaidsleeve, said 4shank havinga lug to disengagezsaid lug from one of saidrecesses to permit rotation of said sleeve.

VIntestimony whereof I alix my signature.
